Frequently Asked Questions

What is the maximum rear projection allowed?

Detached houses may extend up to four metres under standard rules, or eight metres with prior approval. Smaller limits apply to other house types.

Can I add bi-fold doors to my extension?

Yes, provided the extension itself complies with permitted development rules and glazing requirements meet building regulations standards.

Can I build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

Can I extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.

How close can I build to my neighbour’s boundary?

Extensions built close to a boundary must meet height and eaves restrictions, especially if within two metres of the boundary.

Can I build an outbuilding in my garden?

Outbuildings may be permitted development if they meet height, location, and usage restrictions.
